• Scaling on EC2 - Real world experience from the WebMynd team.


• List of Firebug Extensions - There are a bunch here I didn't know about. It's becoming a platform-within-a-platform.


• acts_as_overflowable - Lets a column overflow into a second column. This helps when you want to index text quickly.
